Often a new-born presents respiratory problems, like bronchopneumonia, caused by ingestion of infected amniotic fluid meconium, to get infant diagnostic is necessary to use X-ray radiography.
In this paper we want to evaluate the absorbed doses in neonates undergo a radiograph requested by the doctor. For this reason we try to simulate the real conditions of the hospitals in Lima, in neonatal nurseries where X-rays are performed.
The simulation is made according to the questionary related to technical data of X-ray equipment, distance between the source and the neonate, and its position to be irradiated. The information obtained was used to determine the dose received by infants using the MCNP code. The results are compared with standard values of international health agencies and radiation protection standards.
Below we present 3 common forms of which are from hospitals in Lima when taking radiographs. With these geometries, we calculate the dose delivered to the patient by varying the size and weight of newborns in relation to the distance tube-baby and kVp.
